Select Active Signals from a Waveform Array in LabVIEW

[MXI Master]

Description

Description-Separate-1

1. Overview

This VI take an array of waveforms and selects out only the active signals in a memory efficient manor.

2. Description

Many situations it is more efficient to read all of your data into LabVIEW and then later remove the unused channels. This VI take an array of waveforms and selects out only the active signals in a memory efficient manor. It could be used on any array data type.
The VI gets as inputs the array of waveform from which you want to select some, as well as the array of booleans in which you decide the selection.

3. Requirements

• NI LabVIEW Base Development System 2012 (or compatible).

4. Steps to Implement or Execute Code

1. Download and open the example file "Select Active Signals LabVIEW 2012 NIVerified.vi"
2. In Items Selected connect an array with the signals you want to select. (True to select, false to leave behind).
3. In Input Data wire the signals from which you want to select. They will be added to the Output Data according to their respective state in Items Selected.
4. Run the VI.
